c++ - SDL2和OpenGL - Visual Studio错误LNK2019:无法解析的外部符号

C++ - SDL2 and OpenGL - Visual Studio error LNK2019: unresolved external symbol

本文关键字：符号 外部 LNK2019 SDL2 OpenGL Visual 错误 Studio c++      更新时间：2023-10-16

我正在学习如何使用SDL2，我正在遵循LazyFoo的教程。

我已经从第50课下载了源代码，它教如何使用OpenGL与SDL2(链接到教程)，并试图执行它，但我得到了很多错误，我不知道该怎么办!

错误如下:

我从未使用过OpenGL，所以我不知道发生了什么。

这是什么意思?我该如何解决这个问题?

看起来你丢失了一个库文件，很可能是OpenGL32.lib。如果您有可用的库，请将其添加到您的项目中。
